When Rodrigo Diaz set out to pick up his friends and go ice skating, he was in high spirits. But when his GPS navigation system took him and some friends to the wrong house, he was assumed to be an intruder—and shot dead.

Friends of Diaz claim that the then 69-year-old Phillip Sailors saw the car arrive at his house in Lilburn, Georgia, through a window. Moments later, Sailors appeared in his driveway, firing a gun into the air. As Diaz attempted to drive away, Sailors fired a shot which fatally wounded him.

Since, Sailors has been charged with murder with malice. His lawyer, Michael Puglise, explains:

"He is very distraught over the loss of life from the defense of his home. This incident happened late in the evening hours when he was home with his wife and he assumed it was a home invasion and he maintains his innocence."

Currently, it is Diaz's friends who claim the GPS system provided incorrect directions. It remains to be seen whether that's the case, or whether it had been incorrectly programmed. If it's the fault of the GPS system, though, it could be the biggest navigation blunder yet. [Atlanta Journal-Constitution via CNET]
